Customizable cooling fan system: This feature is helpful after you are done with 3D printing a part or functional prototype. By letting you specify the speed of cooling, Wanhao gives you an opportunity to increase your overall print speed for printing objects on Duplicator 9 Mark II. And by raising the fan, you do not end up in the trouble of non-uniform cooling. Even after increasing the fan speed, the cooling of your parts and functional prototypes are completely uniform.

Unique MK 10 Extruder and high precision sensor: Wanhao has got in place a unique MK 10 Extruder in Duplicator 9 Mark II which provides you the smoothest extruding known in the market. It lets you easily load and unload the 3D printer filament on the printer. It is extremely reliable and the extra cooling fans make your prints sharper than ever. Overall, the extruder increases your print quality.

High precision sensor present inside Duplicator 9 Mark II lets you auto level the bed guaranteeing you that the first layer of your print will not be messed up with. And hence the complete part or functional prototype will be perfectly dimensionally accurate.

HD touch screen user interface and magnetic upper mat: For interacting with the printer in a much friendlier manner, the manufacturer has got in place an HD touch screen user interface. It lets you turn some functions on/off on the 3D printer. Some options like Print, Utilities, Setting, and bed leveling can be done easily using the touch screen user interface.

You have in place in Duplicator 9 Mark II an easy remove the magnetic upper mat. This lets you remove the printed part or functional prototype with ease. The objects that are created can be removed without putting them into any danger of damaging any ends of them.

Resume printing after power interruption: In case you’ve had an unexpected power outage in the middle of the 3D printing process, there is no need to worry about the backup. Duplicator 9 Mark II offers a complete backup of your print progress. The machine will save the work that you’ve done in case of a power outage and let you resume from the same point after the electricity is back in place.

Printing Type/Cost

Wanhao Duplicator 9 Mark II is based on FDM 3D printing technology. Herein a solid filament spool is used to 3D print a part or functional prototype.

The material with which you wish to 3D print an object is fixed in the filament spool holder of the printer. That material is then heated enough to reach the glass transition temperature.

Once it reaches the glass transition temperature, it is allowed to melt via a nozzle system to reach the print bed of the printer.

Layer by layer the part is laid down according to its geometry which is fed to the 3D printer.

3D printing requirements differ for different parts and functional prototypes. Sometimes you may need support structures and rafts, especially while 3D printing hollow structures. And, other times, you may not.

Hence, the overall cost of 3D printing a part depends on the geometry of the object that you are willing to 3D print, the material of the filament, the amount of infill that is needed, and a lot more different attributes.

But generally, 3D printing a part with an FDM 3D printer costs lesser than 3D printing it with other 3D printing technologies.

Print Quality
